Objective:To analyze the literature of Ilizarov methods, visualizing and discussing the research status, research hotspots and research trends.Methods:A bibliometric study on Ilizarov methods was performed. Using keyword "Ilizarov" and the Chinese translations to retrieve Chinese publications from CNKI database, Wanfang DATA, VIP database and SinoMed database. Using keywords "Ilizarov method, Ilizarov technique, Ilizarov treatment" to retrieve English publications from Web of Science Core Collection database before January 2021, extracting the information including author, journal, country, institution, keywords and cited times. Using the tools of bibliometrics and VOSviewer to analyze the data and draw knowledge maps.Results:A total of 1 789 Chinese publications and 1 709 English publications were included. USA, UK and China were on the top 3 list of the number of publications. Orthopaedic Journal of China, Chinese Journal of Orthopaedic Trauma, Chinese Journal of Reparative and Reconstructive Surgery, Chinese Journal of Orthopaedics, and Chinese Journal of Bone and Joint Surgery published the most literature. 7 English journals were identified as core journals in the field of Ilizarov methods, among which Clinical Orthopaedics and Related Research, Journal of Bone and Joint Surgery (British Volume), International Orthopaedics were JCR Q1 journals. According to the visualized keywords co-occurrence clusteranalysis, the research topics in Chinese literature could be sorted into 6 clusters, the latest hotspots were bone nonunion caused by infection and the treatment for the diabetic foot. In the English literature, the research topics could be sorted into 4 clusters, while the latest topics were infected and posttraumatic bone defects. Conclusion:The number of research on Ilizarov methods is increasing around the world, researches from China are gradually becoming one of the main forces. The research trends at home and at abroad are the same in essentials while differing in minor points, and researches with Chinese characteristics are developing. The strengthening of international cooperation is essential to the development of Ilizarov methods.

Objective To evaluate the value of the thumper cardiopulmonary resuscitator in the emergency cardiopulmonary resuscitation(CPR).Methods Fifty cardiac mspiratory sudden stop patients with thumper cardiopulmonary resuscitator from January 2004 to December 2007 were recruited into treatment group,and 80 cardiac respiratory sudden stop patients with barehanded CPR from May 2000 to December 2003 were recruited into control group.The SBP and blood oxygen saturation 5 to 10 minutes after the resuscitation was compared.The rate of restoration of spontaneous circulation(ROSC),hospitalization and the complication in the two groups was compared.Results The treatment group was better than the control group in improving the SBP and blood oxygen saturation(P＜0.05).The rates of ROSC and hospitalization in the treatment group were higher than those in the control group(44%,40%and 25%,21%).P＜0.05.The rate of complications had no significant difference between the two groups.Conclusions Thumper cardiopulmonary resuscitator Can surmount the factors of medical staff or patients.It can make the CPR more standard andmore effective.MeanwhileitCan raisethe SBP,strokevolume and blood supplv to the heart and brain,and then mcrease the successful rate of CPR.

Objective To evaluate the correlation between imaging features of spiral computed tomography(SCT) and pathology, MVD, and the expression of VEGF in renal cell carcinoma(RCC). Methods Thirty patients with RCC diagnosed by pathology underwent SCT examinations.MVD and the expression of VEGF were examined immunohistochemically using SABC techniques. Results The detection and characterization rate as well as accuracy of staging before operation about 30 RCC of multiphasic SCT scans were 100 %, 100 % and 83.3 %, respectively. In 30 cases of RCC, the mean MVD was 36±12.4. The positive expression rate of VEGF were 73.33 %. There were no correlation between the MVD and the expression of VEGF in RCC (r =0.057, P >0.05). The features of SCT: on multiphasic SCT scans, the pathological nuclear grade, the MVD and positive expression of VEGF in groups of RCC with diameter larger than 3.0 cm, central necrosis, pseudocapsule and intravenous tumor emboli were obviously higher than those of the contrast group (P <0.05, P <0.05, P <0.05, respectively). The pathological nuclear grade and MVD in groups of RCC with lymph node metastasis were higher than the contrast group (P <0.05, P <0.05, respectively). There were the positive correlation between the enhanced Hounsfield' s units in the CMP and the MVD in 30 cases of RCC(r =0.784, P <0.05). The degree of enhancement correlated well positively with the MVD in 30cases of RCC (P < 0.05). Conclusion Multiphasic enhanced SCT scan is a reliable technique in the detection, pathologic characterization of RCC. Some SCT features are closely correlated with MVD and expressions of VEGF in RCC, which could be a noninvasive method in predicting aggressiveness and metastasis.

Objective To analyze the situation and study trend of large-scale nurses'health cohort studies based on Web of Science,to help design clinical guidelines and scientific research for nursing staff in China.Methods Articles of large nurses'health cohort studies published from 1993 to 2023 were retrieved from Web of Science(WOS)Core Collection.Citespace and Bibilometrix were used to perform the bibliometric analysis.Results 2882 studies were included in this study.Total volume of papers was enlarging by year.Clustering results showed that the main keywords could be divided into 3 categories:risks of women's health,risks of cardiovascular disease and reproducibility.Results of keywords burst showed that lifestyle,cardiovascular disease,women reproductive health and mental health were the highlights of studies in recent 5 years.Conclusion Research on large-scale nurse health cohorts holds significant scientific significance.It is recommended to establish a nationwide large-scale nurse health cohort as soon as possible.In the study,appropriate exposure factors should be selected,with reproductive health,mental health,and psychiatric disorders being the primary outcome measures,and chronic physical illnesses being the secondary outcome measures.By systematically describing the factors influencing the physical and mental health of nurses in China,we can better safeguard their well-being and promote the development of the nursing discipline.
